Solve for x<br><img src="https://tex.z-dn.net/?f=6x%20-%202%20%3D%204x%20%2B%2013" id="TexFormula1" title="6x - 2 = 4x + 13" alt
solniwko [45]

x = \frac{15}{2}

subtract 4x from both sides of the equation

6x - 4x - 2 = 13

2x - 2 = 13

add 2 to both sides

2x = 13 + 2 = 15

divide both sides by 2

x = \frac{15}{2}

What is the value of X? (geometry, right triangles)
Dahasolnce [82]

Answer:

C

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin30° = \frac{1}{2} , then

sin30° = \frac{opposite}{hypotenuse} = \frac{x}{10} = \frac{1}{2} ( cross- multiply )

2x = 10 ( divide both sides by 2 )

x = 5 → C

Help math<br>look at pic​
Sloan [31]

Answer: \Large\boxed{(-4,~-3)~\text{and}~(-2,~1)}

Step-by-step explanation:

<u>Given the system of equation</u>

1)~y=-(x+2)^2+1

2)~y=2x+5

<u>Expand the parenthesis of the 1) equation</u>

y=-(x+2)^2+1

y=-(x^2+4x+4)+1

y=-x^2-4x-4+1

y=-x^2-4x-3

<u>Current System</u>

1)~y=-x^2-4x-3

2)~y=2x+5

<u>Substitute the y value of the 1) equation with the 2) equation</u>

2x+5=-x^2-4x-3

<u>Add ( x² + 4x + 3) on both sides</u>

2x+5+(x^2+4x+3)=-x^2-4x-3+(x^2+4x+3)

2x+5+x^2+4x+3=0

<u>Combine like terms</u>

x^2+2x+4x+5+3=0

x^2+6x+8=0

<u>Factorize the quadratic equation</u>

(x+4)(x+2)=0

x=-4~\text{or}~x=-2

<u>Substitute the x values into one of the equations to find the y value</u>

y=2x+5

y=2(-4)+5=-8+5=-3

y=2(-2)+5=-4+5=1

<u>Therefore, the two solutions are:</u>

\Large\boxed{(-4,~-3)~\text{and}~(-2,~1)}

Hope this helps!! :)

Two women start at the same point. they walk in opposite directions for 3 meters, then turn right and walk another 4 meters. how
8_murik_8 [283]

The total distance between the two women would simply be the sum of the hypotenuse formed by the triangular path they created.

For each women:

<span>c^2  = a^2 + b^2</span>

c^2 = 3^2 + 4^2

c^2 = 9 + 16

c^2 = 25

c = 5 m

Therefore the distance between the two is:

distance between the two women = 2 * c

<span>distance between the two women = 10 m</span>
